To get the biggest yields, keep your CFLs as close to your buds as possible (without burning them!)

Some growers will include both a vegetative and flowering section, or they might dedicate the whole box to one grow.

4.) Total Yields to Expect from CFLs (0.25g/watt)

Besides basic plant care, the best way you can increase cannabis yields under CFLs in the vegetative stage is to train your plants to grow short and wide so they’re best able to best take advantage of the CFL’s great light spectrum in the flowering stage. Plant training will dramatically increase your yields!

Avoid Shadowy Areas – If you see a “shadowy” area on the plant, it means you need another bulb there, or need to use bending (LST) to rearrange the shape of the plant so all parts are getting direct light.

You can grow marijuana with CFL grow light bulbs in soil or hydroponically. Regardless of the growing medium, light needs remain the same.

If you are trying to do a single CFL grow operation with only one bulb, you need a small plant that flowers quickly, like an autoflower variety. Keep in mind that the yield of cannabis will be low with this setup. But, if you can’t spare more room than this, it’s still doable multiple times a year!

How To Grow With CFL

They come in a variety of different bases, so flexibility when designing a grow operation won’t be a problem. CFL lights don’t use excessive energy and don’t heat up as high as some other specialized grow lights for marijuana.

Pros & Cons Of CFL Lights For Growing Weed

As mentioned, the coverage of one CFL bulb will only produce enough light exposure to about 12 inches away from the bulb itself. This means that you’ll probably need multiple lights per plant to account for lateral growth.

As the plants get taller and start blooming, you may need to get a couple more CFLs to light them from the sides. Basically if you see any dark or shadowy areas that are more than 6 inches from a CFL, then you should get another CFL to plug in that ‘hole.’

When looking for clamp light sockets, avoid anything that’s made of plastic (it’s cheap and will break) and try to find something with at least a 9-foot-long cord. You might be surprised at how annoying it is to try to find a way to make a 6-foot cord work.

Despite all my mistakes, I still got 6.2 ounces of dried buds off my first plant grown with this grow method!

When not using nutrients, make sure you still pH your plain water before your feed your marijuana!

It’s optimal to use ‘daylight’ (6500k) colored bulbs for the vegetative stage and ‘soft white’ (2500k) colored bulbs for flowering, but you can use any color CFL during either stage and your plant will grow well. The color spectrum of the bulb is not nearly as important as the total wattage.

Instead of just plain sockets, you may decide to get some heavy duty clamp light sockets which you can use to power your light bulbs. These light sockets have a reflector built in and are able to clamp to most anything.

Flowering Stage

Each additional plant needs an additional container, coco and 5 more CFLs and light sockets, for an additional setup cost of about $100/plant.

60 grams) per plant of bud retail value: You may get even more but a reasonable estimate for someone who follows the directions is to harvest at least two ounces of dried bud from each plant. At $10-$20/gram (prices around here), two ounces of cannabis is equal to $566 – $1133 which is worth much more than the money you need to put in to get started. And the amount you spend will go down each grow, while your yields will likely go up. Plus, you don’t have to go anywhere to get your buds! I got a total 6.2 ounces of dried buds off my first cannabis plant I grew using this system (pictured below in flowering section) but to get those kinds of results you need to train your plant and invest in more CFLs as the plant get bigger to make sure there aren’t any shadowy areas.
